This removes the related tests, and puts the related specs behind
version guards.  This affects all code in lib, including some
libraries that may want to support older versions of Ruby.

It breaks backward compatibility than I thought. So it's disabled by
default. It means that REXML's XPath processor isn't compatible with
XPath 1.0. But it will be acceptable for users.

We can enable it by specifying "strict: true" to
REXML::XPathParser.new explicitly.

* lib/rexml/xpath.rb,
  lib/rexml/xpath_parser.rb: Accept "strict: true" option.

* test/rexml/test_contrib.rb,
  test/rexml/xpath/test_base.rb: Use not XPath 1.0 compatible behavior.

* test/rexml/test_jaxen.rb: Use XPath 1.0 compatible behavior.

* test/rss/test_1.0.rb,
  test/rss/test_dublincore.rb,
  spec/ruby/library/rexml/element/namespace_spec.rb,
  spec/ruby/library/rexml/element/namespaces_spec.rb,
  spec/ruby/library/rexml/element/prefixes_spec.rb: Enable again.

r63236 (or r63237) introduces test failures and CI shows errors.
This commit makes skipping these tests.  Please revert this commit
after tests (and rubyspec) work fine.

Fix GH-1725

<itunes:explicit> accepts "explicit", "yes", "true", "clean", "no" and
"false" as valid values.

Here is the <itunes:explicit>'s description in
https://help.apple.com/itc/podcasts_connect/#/itcb54353390:

> The <itunes:explicit> tag indicates whether your podcast contains
> explicit material. You can specify the following values:
>
>   * Yes | Explicit | True. If you specify yes, explicit, or true,
>     indicating the presence of explicit content, the iTunes Store
>     displays an Explicit parental advisory graphic for your podcast.
>
>   * Clean | No | False. If you specify clean, no, or false, indicating
>     that none of your podcast episodes contain explicit language or
>     adult content, the iTunes Store displays a Clean parental
>     advisory graphic for your podcast.

I don't know whether <itunes:explicit> value is case sensitive or
insensitive. But the current implementation is case insensitive.

When you change this to true, you may need to add more tests.
